Description

Heat exchanger

Technical Field

The utility model relates to a heat exchange device.

Background

A heat exchanger has appeared in the prior art, which is used for cooling a heat exchange medium (such as water), and specifically, the heat exchange device comprises a heat exchange module and a fan, wherein the heat exchange module is formed by stacking a plurality of plate-type heat exchange fins, a channel for the heat exchange medium to flow is formed by butt joint of the plurality of plate-type heat exchange fins, and a gap for the air flow to pass through is formed between two adjacent plate-type heat exchange fins.

The heat exchange module is internally provided with a cavity surrounded by plate type heat exchange fins, the cavity is provided with a cavity opening, the fan is arranged in the cavity opening, the fan operates to suck air into the cavity, the air continuously passes through the gap between the plate type heat exchange fins and enters the cavity, and when the air flow passes through the gap, the heat of a heat exchange medium is taken away and finally discharged through the fan.

However, if the heat exchanger is operated in a dusty environment, dust may adhere to the side walls of the gap due to the airflow passing through the gap.

In order to remove the dust attached to the side wall, the prior art adopts a mode of reversely operating the fan, namely, the fan blows air flow into the cavity, so that the air flow passes through the gap from inside to outside to take away the dust.

However, the flow velocity of the air flow blown to the gap is not high enough to blow away the dust with strong adhesion due to the limitation of the operating power of the fan, and thus, the above-mentioned method in the prior art has a poor effect of removing the dust.

The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 to 4, an embodiment of the present invention discloses a heat exchange device, which includes a plurality of heat exchange modules 10, a fan 20 and a plurality of shutters 30.

Each group of heat exchange modules 10 is formed by stacking a plurality of plate heat exchange plates, and as is known, a channel for a heat exchange medium to flow is formed inside the stacked plate heat exchange plates. The multiple groups of heat exchange modules 10 are in butt joint in sequence. A liquid inlet and a liquid outlet of the heat exchange medium communicated with the channel are formed at the top of the heat exchange module 10.

The front side wall and the rear side wall of the butted heat exchange modules 10 are planes, a cavity 11 is formed inside the butted heat exchange modules 10, the cavity opening 111 of the cavity 11 faces the front side of the device, and a gap formed between the plate type heat exchange plates penetrates through the cavity 11 and the side walls.

A plurality of louvers 30 are provided outside each side wall, and the plurality of louvers 30 correspond to the plurality of sets of heat exchange modules 10 one by one. The blades of each louver 30 are heat exchange fins 31.

The fan 20 is installed at the mouth 111 of the cavity 11.

The working principle of the heat exchange device is as follows:

as shown in fig. 3, when the heat exchange medium circulating in the channel needs to be cooled, all the shutters 30 are opened, the fan 20 is rotated forward, the fan 20 sucks the air in the cavity 11 to form a negative pressure in the cavity 11, and thus, the outside air passes through the gap from the outside to the inside of the cavity 11, and further takes away the heat of the heat exchange medium.

When dust removal is required, one of the shutters 30 is alternately opened, the other shutters 30 are closed, the fan 20 is rotated reversely, the fan 20 blows air into the cavity 11, and the amount of air blown by the fan 20 passes through only the gap corresponding to the opened shutter 30, so that the flow velocity of the airflow passing through the gap is high, and dust attached to the side wall of the gap can be carried away.

The utility model provides a heat transfer device's advantage lies in:

the plurality of louvers 30 are installed outside the side wall of the heat exchange module 10, and only one louver 30 is alternately opened, so that the flow cross section of the air flow is reduced, the flow velocity of the air flow is increased, and the dust removal efficiency is improved.
